Governors in the German states are called Ministerpräsident or Minister President or Premier. They are president of those ministers, who run the various departments of a state. The state parliaments have the same structure as the Bundestag, Germany‘s national parliament.
The minister president is a colleague among the members of the state parliament‘s largest elected faction and is elected by his or her colleagues to form a government, typically a coalition of two parties.
The minister presidents, like the chancellor, manage and coordinate the work of the ministers, who, however, lead their departments independently. The minister president is a primus inter pares, a first among equals.
Like the ministers at the federal level, the ministers at the state level are powerful political figures from the regions of the state. Each is capable, and in most cases willing, to become minister president. The acting minister president, therefore, has to balance out carefully the interests of these power brokers.
Germans mayors are called Bürgermeister. Again, like the chancellor and the minister presidents, the Bürgermeisters are selected by their colleagues in the largest elected party in their city councils. They form a city government, typically a coalition of two parties.
And like the chancellor and the minister presidents, the mayor is a primus inter pares, managing powerful local politians who head up the city‘s most important departments.
