Partitions of Poland
In 1730 Commonwealth's neighbours, namely Prussia, Austria and Russia, signed a secret agreement in order to maintain the status quo: specifically, to ensure that the Commonwealth laws would not change. Their alliance later became known in Poland as the "Alliance of the Three Black Eagles" (or Löwenwolde's Treaty), because all three states used a black eagle as a state symbol (in contrast to the white eagle, a symbol of Poland).
