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.
