Other Emigrants
Besides former German citizens, their descendants and members of their families (usually a party of a mixed marriage – autochthon and nonautochthon) other Polish citizens also emigrated to Germany after World War II. The exact numbers are difficult to estimate. It is known that in the 1980s around 300,000 Poles left Poland (usually illegally) and settled in Western Germany. Among many true political emigrants, some of these people only claimed to be such, in fact emigrating for economic reasons. This so-called "Solidarity emigration" involved a high number of people with secondary and higher education. They were characterised by possessing deep national pride, and actively participate in Polish cultural and political life in Germany. Few of them returned to Poland after the fall of communism in 1989 (see Polish Round Table Agreement and Contract Sejm).
