Since German reunification on 3 October 1990, the unemployment rate in Germany had risen from 4.2% to 9.4% in 1998, with the Federal Labor Office registering more than 4 million unemployed. The unified Germany had to fight economic and domestic difficulties even as it actively participated in the project of European integration. Most people blamed the centre-right coalition government of the Christian Democratic Union/Christian Social Union (CDU/CSU) and the Free Democratic Party (FDP) for the economic difficulties. Longtime Chancellor Helmut Kohl's government was regarded by many as not having fully implemented the unification after eight years, in view of the mass protests in many eastern German towns due to job losses and social welfare cuts.
