This period saw the Knights consolidating their control over Prussia and extending their influence into areas that are now part of modern-day Poland, Lithuania, and Latvia.\r\n\r\nThe administrative center of the State of the Teutonic Order was Marienburg Castle, which served as the key political and military hub. The state was characterized by a highly militarized society, with the Knights forming the ruling class. They established a network of castles and fortified towns throughout their territories to secure their control and facilitate further expansion. §REF§Jürgen Sarnowsky, Der Deutsche Orden, 3., durchgesehene Auflage., C.H.

                "general_description": "The Roman Principate (31 BCE-284 CE) refers to the first period of the Roman Empire, when the de facto ruler was termed the <i>princeps</i>, or 'leading citizen'. The period begins with the victory of the first emperor, Augustus (then Octavian) over his rival Mark Antony at the Battle of Actium in 31 BCE and ends with the accession of Diocletian after the 'crisis' of the 3rd century CE (235-284 CE). §REF§ (Boatwright et al. 2012) Mary T.

New York: Oxford University Press. §REF§ <br>Retaining and solidifying many of the institutions, cultural forms, and economic base that had led to Rome's hegemonic position during the Republican period, the Empire became one of the largest, most long-lived, and most prosperous imperial states the world has ever known. Augustus established a dynasty lasting until the death of the Emperor Nero in 68 CE, after which followed a brief civil war between different potential successors. Despite repeated bouts of similar warfare during succession crises following the various dynasties that ruled the Principate, the Empire remained remarkably stable throughout this period. Rome was able to unite - and keep together - a huge swathe of territory encompassing all of western Europe, North Africa, Egypt, the eastern Mediterranean, most of Anatolia, and parts of the Near East. Integrating diverse regions into this single empire facilitated the spread of Roman institutions - notably its legal system, urban infrastructure, cultural forms, and political structure. It also promoted economic development by enabling the safe transport of goods and people to every corner of the empire. §REF§ (Bowman and Wilson 2009) Alan K. Bowman and Andrew Wilson. 2009.

Oxford: Oxford University Press. §REF§  It was during this period that Rome built some of its greatest structures: the Pantheon, the Coliseum, the imperial <i>fora</i> (market squares) in the heart of Rome, and many others. The Principate overall produced so much wealth and so many cultural achievements that the great 18th-century English historian Edward Gibbon proclaimed the Empire at its peak in the 2nd century CE to be 'the period in the history of the world, during which the condition of the human race was most happy and prosperous'. §REF§ (Gibbon [2003] 1869, 53) Edward Gibbon. [2003] 1869. <i>The Decline and Fall of the Roman Empire</i>, edited by Hans-Friedrich Mueller. New York: Modern Library. §REF§ <br>In the late 3rd century CE, beginning after the end of the Severan Dynasty, the Principate nearly collapsed in the face of internal warfare and pressure from external foes, including the Sassanid Persian Empire and nomadic tribes from Germany and eastern Europe. Rome briefly lost control over parts of France, Britain, and southern Spain and suffered several significant losses in battle to the Sassanids. Under first the Emperor Aurelian (r. 270-275 CE) then Diocletian (r. 284-305), however, all territory was recovered and a series of administrative and economic reforms inaugurated a second phase of the Roman Empire, which we refer to as the Dominate (denoting the increasing centralization of authority and the development of a large bureaucratic apparatus).<br><i>Population and political organization</i><br>Nominally, there was no change in political organization between the Republican period and the Principate. The first princeps, Augustus, kept all Republican institutions and offices, including the Senate, intact. There was clear practical change in the power structure, however, as Augustus, and all emperors after him, asserted personal control over almost the entire Roman army and were granted unprecedented legislative, religious, and judicial powers to shape politics and Roman society at large. Whereas a defining principle of Republican governance was that no individual should be able to hold multiple offices simultaneously, amassing power in several domains (military, legislative, religious, and so on), emperors broke this tradition and drew their authority from numerous offices, titles, and the authority they carried. §REF§ (Noreña 2010) Carlos Noreña. 2010. 'The Early Imperial Monarchy', in <i>The Oxford Handbook of Roman Studies</i>, edited by A. Barchiesi and W. Scheidel, 533-46. Oxford: Oxford University Press. §REF§ <br>The Roman emperor was also generally one of the wealthiest people in the Principate, controlling huge agriculturally productive estates throughout the Empire, particularly in North Africa and Egypt. §REF§ (Kehoe 2007) Dennis P. Kehoe. 2007. <i>Law and the Rural Economy in the Roman Empire</i>. Ann Arbor, MI: University of Michigan Press. §REF§  In this period, state revenues were split between the 'public' treasury (<i>aerarium</i>) and an imperial treasury (<i>fiscus</i>) under the direct control of the emperor. §REF§ (Adkins and Adkins 1998, 45) Lesley Adkins and Roy A. Adkins. 1998. <i>Handbook to Life in Ancient Rome</i>. Oxford: Oxford University Press. §REF§  The Principate had a fairly limited reach, particularly outside of Italy, but the state did have some significant expenses which it met by collecting tax from the Empire's vast territory and large population, taking in rents from the imperial estates. In addition to paying the salaries of imperial officials - a relatively small expense as only limited central authority was exerted in the provinces (mainly the provincial governors and their retinue) - the emperor was responsible for financing a professional citizen army, the major state expense along with public works projects such as roads, aqueducts, and temples. The costs of these public works, though, were split between the personal fortune of the emperors who acted as patrons, particularly in Italy, and that of wealthy patrons in the provinces, who financed much of the urban growth in these regions. Further, beginning in the later Republican period and continuing throughout the Empire, the imperial state provided grain at reduced prices to citizens living in Rome; another considerable expense. §REF§ (Duncan-Jones 1994) Richard Duncan-Jones. 1994. <i>Money and Government in the Roman Empire</i>.

Roman provinces were governed by fairly autonomous officials (<i>procurator</i>, <i>curator</i>, <i>praefectus</i>, <i>proconsul</i>, etc.) and priests (<i>flamen</i>, etc.). §REF§ (Talbert 1996) Richard J.

Berkeley, CA: University of California Press. §REF§  Urbanization was also encouraged throughout the Empire; provincial cities were administered as 'mini-Rome's, with local urban equivalents of the Senate and most administrative, judicial, and religious magistracies. Roman cultural and infrastructural achievements were widely mimicked, with aqueducts, temples, theatres, bathhouses, and material culture (for example, particular ceramic forms, a culture of communal feasting, and the habit of publicizing achievements with inscribed stone tablets) adapted by numerous provincial towns and cities. §REF§ (Wilson 2011) Andrew Wilson. 2011.

                "general_description": "The last of the Roman kings, the tyrannical Lucius Tarquinius Superbus ('the Arrogant'), was expelled by a revolt of some of the leading Roman aristocrats in 509 BCE. Vowing never again to allow a single person to amass so much authority, the revolutionaries established in place of the monarchy a republican system of governance, featuring a senate composed of aristocratic men and a series of elected political and military officials. The Roman Republic was a remarkably stable and successful polity, lasting from 509 BCE until it was transformed into an imperial state under Augustus in 31 BCE (though the exact date is debated, as this was not a formal transformation). We divide the Republic into an early (509-264 BCE), a middle (264-133 BCE), and a late (133-31 BCE) period.<br>During the 3rd century BCE, Rome fought two separate wars (264-241 BCE and 218-201 BCE) against the Punic people, inhabitants of a former Phoenician colony in North Africa, Sicily, and southern Spain. The latter conflict featured a bitter contest against the famous Punic general Hannibal, who nearly defeated the Romans on his dramatic march through Italy from 218 to 216 BCE. However, Rome recovered, won control of Punic holdings in Sicily and Spain, and established what were essentially vassal kingdoms in North Africa. In the early 2nd century BCE, Rome became embroiled in another series of wars in Greece, Macedonia, and Anatolia. The 3rd and 2nd centuries were a somewhat chaotic time in the eastern Mediterranean, following the fragmentation of Alexander the Great's Macedonian Empire after his death in 323 BCE. Alexander's Empire had essentially dissolved into a series of successor states, which engaged in near-constant warfare in their attempts to expand at the others' expense. §REF§ (Eckstein 2006, chapter 4) Arthur M. Eckstein. 2006. <i>Mediterranean Anarchy, Interstate War, and the Rise of Rome</i>. Berkeley, CA: University of California Press. §REF§  By 148 BCE, at the conclusion of the fourth and final Macedonian War, Rome was either in possession of or was firmly established as hegemon over the entire Mediterranean basin, from Spain in the west to Anatolia in the east, and France in the north to Libya and Egypt in the south. This position brought new territory along with a flood of new peoples, culture, and wealth from the ancient civilizations in Greece, Egypt, and Anatolia. By the end of the Middle Republic period, Rome was virtually unchallenged by external enemies, although this newfound wealth and power was accompanied by the period of internal turmoil that characterized the Late Republic.<br><i>Population and political organization</i><br>Rome during the Republican period possessed no written constitution, but was governed largely through the power and prestige of the Senate, with a clear respect for precedent and for maintaining Rome's traditions. §REF§ (Brennan 2004, 31) Corey T. Brennan. 2004. 'Power and Process under the Republican \"Constitution\"', in <i>The Cambridge Companion to the Roman Republic</i>, edited by Harriet I. Flower, 31-65. Cambridge: Cambridge University Press. §REF§  A primary goal of the early Republic was to establish clear checks on the power of any single ruler - the military office of chief commander was in fact split between two generals (consuls), while the chief priestly and legislative posts were split among different people (individuals were restricted from holding multiple offices at once) - and popular assemblies voted on new laws.<br>Romans of this period did not distinguish between what is today termed 'secular' and 'sacred' authority; although individual magistracies had distinct functions, the same person often held both religious and political offices over the course of their lifetime, as they were thought to be part of essentially the same sphere of governance. The Republic featured a substantial array of religious offices and institutions intended to determine the will of the gods or to please them through the proper performance of rituals and the maintenance of large public temples. §REF§ (Brennan 2004, 37) Corey T.

                "general_description": "The archaeological site of Jenne-jeno (or Djenné-djenno) is a mound located in the Niger Inland Delta, a region of West Africa just south of the Sahara and part of modern-day Mali, characterized by lakes and floodplains. It was continuously inhabited between 250 BCE and 1300 CE. 'Jenne-jeno IV' refers to the period from 900 to 1300 CE. This roughly corresponds to the tail end of the region's 'urban prosperity' phase, and the beginning of the 'urban shake-up'. §REF§ (McIntosh 2006, 175-76) Roderick McIntosh. 2006. <i>Ancient Middle Niger</i>. Cambridge: Cambridge University Press. §REF§  By this period, the inhabitants of Jenne-jeno had established long-distance trade networks and developed bronzeworking. Around 1000, they started working with brass, and the population continued to grow, reaching its peak between 1100 and 1200. They also produced an impressive corpus of terracotta figurines. However, in the 13th century, the population decreased rapidly, eventually leading to the abandonment of several sites, Jenne-jeno included, by 1400. The reasons for the decline are unclear, but they may include climate change, pandemic diseases such as plague, cultural upheaval deriving from the arrival of Islam and horses, and the emergence of the great West African empires of Ghana, Mali and Songhai. §REF§ (McIntosh 2006, 176-177) Roderick McIntosh. 2006. <i>Ancient Middle Niger</i>. Cambridge: Cambridge University Press. §REF§ <br><i>Population and political organization</i><br>No population estimates could be found specifically for this period. However, the combined population of Jenne-jeno and its satellites within a one-kilometre radius had probably reached 10,000-26,000 people by 800 CE. The population continued to grow until 1200, and then rapidly declined in the 13th and 14th centuries. §REF§ (McIntosh 2006, 174-77) Roderick McIntosh. 2006. <i>Ancient Middle Niger</i>. Cambridge: Cambridge University Press. §REF§ <br>The political organization of Jenne-jeno may have been quite different from that of other ancient cities. In several decades of excavation, clear evidence for hierarchies of any kind has yet to be unearthed: it seems that Jenne-jeno had no palaces, rich tombs, temples, public buildings, or monumental architecture. Indeed, the city's very layout ‒ an assemblage of dispersed clusters ‒ suggests a resistance to centralization. §REF§ (McIntosh 2006, 189) Roderick McIntosh. 2006. <i>Ancient Middle Niger</i>. Cambridge: Cambridge University Press. §REF§  It is possible that, at this time, Niger Inland Delta society was organized 'heterarchically' rather than hierarchically: that is, it was divided into multiple components, each deriving authority from separate or overlapping sources, with mechanisms in place to prevent any one group from monopolizing power. §REF§ (McIntosh 2006, 228-29) Roderick McIntosh. 2006. <i>Ancient Middle Niger</i>.

It was continuously inhabited between 250 BCE and 1400 CE. 'Jenne-jeno III' refers to the period from 400 to 900 CE. This roughly corresponds to the region's 'urban prosperity' phase. §REF§ (McIntosh 2006, 175-76) Roderick McIntosh. 2006. <i>Ancient Middle Niger</i>. Cambridge: Cambridge University Press. §REF§  Though subsistence strategies remained largely unchanged, a number of important transformations occurred: the inhabitants of Jenne-jeno grew in number, established long-distance trade networks, and developed more sophisticated metalworking techniques. §REF§ (McIntosh and McIntosh 1981, 1) Roderick J.

Cambridge: Cambridge University Press. §REF§ <br><i>Population and political organization</i><br>Between 400 and 800 CE, Jenne-jeno grew from 25 to 33 hectares. Population density was likely high, and a conservative estimate puts the population of Jenne-jeno and its satellites within a one-kilometre radius at 10,000-26,000 people around 800 CE. §REF§ (McIntosh 2006, 174-75) Roderick McIntosh. 2006. <i>Ancient Middle Niger</i>. Cambridge: Cambridge University Press. §REF§ <br>The political organization of Jenne-jeno may have been quite different from that of other ancient cities. In several decades of excavation, clear evidence for hierarchies of any kind has yet to be unearthed: it seems that Jenne-jeno had no palaces, rich tombs, temples, public buildings, or monumental architecture. Indeed, the city's very layout ‒ an assemblage of dispersed clusters ‒ suggests a resistance to centralization. §REF§ (McIntosh 2006, 189) Roderick McIntosh. 2006. <i>Ancient Middle Niger</i>. Cambridge: Cambridge University Press. §REF§  It is possible that, at this time, Niger Inland Delta society was organized 'heterarchically' rather than hierarchically: that is, it was divided into multiple components, each deriving authority from separate or overlapping sources, with mechanisms in place to prevent any one group from monopolizing power. §REF§ (McIntosh 2006, 228-29) Roderick McIntosh. 2006. <i>Ancient Middle Niger</i>.
