summaryLong: German reunification, also known as the expansion of the Federal Republic of Germany (BRD), was the process of re-establishing Germany as a single sovereign state, which began on 9 November 1989 and culminated on 3 October 1990 with the dissolution of the German Democratic Republic and the integration of its re-established constituent federated states into the Federal Republic of Germany to form present-day Germany. This date was chosen as the customary German Unity Day, and has thereafter been celebrated each year as a national holiday. On the same date, East and West Berlin were also reunified into a single city, which eventually became the capital of Germany.
lede: On October 3, 1990, Germany officially reunified after 28 years of division, merging the Federal Republic of Germany (West) with the German Democratic Republic (East). The process accelerated after the Berlin Wall fell on November 9, 1989, and concluded with the signing of the Treaty on the Final Settlement with Respect to Germany in September 1990, which secured international approval from the Soviet Union, United States, France, and Britain.

impactStatement: Reunification ended the Cold War's most visible symbol, redrew European geopolitics, and created a single German state with 78 million people and significant economic clout. The process required negotiating the withdrawal of Soviet troops, integrating two incompatible economies, and rewriting the continent's security architecture-consequences still shaping EU and NATO policy today.

zeitgeistNote: "October 3, 1990 marked the cultural moment when the Cold War officially ended in Europe. East German citizens experienced rapid consumer culture shock while West Germans grappled with identity loss. The decade saw competing narratives: euphoria about freedom versus anxiety about economic displacement and national identity. German cinema and literature became obsessed with Stasi memory and the experience of two separate societies merging into one."
