Today is the 225th anniversary of the Third Partition of Poland in 1795.
There is an online account of the events at Third Partition of Poland
The causes and consequences of the three partitions are complex and fraught with hubris and failings, with national rivalries, aspirations and delusions, and with misunderstood history and historical narratives. Partition did not resolve them, nor did the resurrection of Poland in 1919-20. It is a history more people should reflect upon than I suspect do.
