Berg was a state—originally a county, later a duchy—in the Rhineland of Germany. Its capital was Düsseldorf. It existed as a distinct political entity from the early 12th to the 19th centuries.

Brandenburg-Prussia is the historiographic denomination for the Early Modern realm of the Brandenburgian Hohenzollerns between 1618 and 1701. Based in the Electorate of Brandenburg, the main branch of the Hohenzollern intermarried with the branch ruling the Duchy of Prussia, and secured succession upon the latter's extinction in the male line in 1618. Another consequence of the intermarriage was the incorporation of the lower Rhenish principalities of Cleves, Mark and Ravensberg after the Treaty of Xanten in 1614.

Bremen-Verden, formally the Duchies of Bremen and Verden, were two territories and immediate fiefs of the Holy Roman Empire, which emerged and gained imperial immediacy in 1180. By their original constitution they were prince-bishoprics of the Archdiocese of Bremen and Bishopric of Verden.

Its history is closely related to that of its southern neighbours: the Duchies of Jülich and Berg, as well as Guelders and the Westphalian county of Mark. The Duchy was archaically known as Cleveland in English.

The Duchy of Westphalia was a historic territory in the Holy Roman Empire, which existed from 1180. It was located in the greater region of Westphalia, originally one of the three main regions in the German stem duchy of Saxony and today part of the state of North Rhine-Westphalia.

The Duchy of Württemberg was a duchy located in the south-western part of the Holy Roman Empire. It was a member of the Holy Roman Empire from 1495 to 1806. The dukedom's long survival for nearly four centuries was mainly due to its size, being larger than its immediate neighbors. During the Protestant Reformation, Württemberg faced great pressure from the Holy Roman Empire to remain a member. Württemberg resisted repeated French invasions in the 17th and 18th centuries. Württemberg was directly in the path of French and Austrian armies who were engaged in the long rivalry between the House of Bourbon and the House of Habsburg. In 1803, Napoleon raised the duchy to be the Electorate of Württemberg of the Holy Roman Empire. On 1 January 1806, the last Elector assumed the title of King of Württemberg. Later that year, on 6 August 1806, the last Emperor, Francis II, abolished the Holy Roman Empire.

When the German Empire came into existence in 1871, none of its constituent states had any overseas colonies. Only after the Berlin Conference in 1884 did Germany begin to acquire new overseas possessions, but it had a much longer relationship with colonialism dating back to the 1520s. Before the end of the Holy Roman Empire in 1806, various German states established chartered companies to set up trading posts; in some instances they also sought direct territorial and administrative control over these. After 1806, attempts at securing possession of territories overseas were abandoned; instead, private trading companies took the lead in the Pacific while joint-stock companies and colonial associations initiated projects elsewhere, although many never progressed beyond the planning stage.

The Reformation was a major movement within Western Christianity in 16th-century Europe that posed a religious and political challenge to the Catholic Church and in particular to papal authority, arising from what were perceived to be errors, abuses, and discrepancies by the Catholic Church. The Reformation was the start of Protestantism and the split of Protestantism from the Roman Catholic Church.
