### Instruction:
What is the most invaded country in history?

### Response:
The most invaded country in history is difficult to determine definitively as there are many variables to consider. However, one country that has been invaded numerous times throughout its history is Poland. Poland has a long history of being invaded and occupied by various neighboring powers. In the 18th century, it was partitioned three times by Russia, Prussia, and Austria, and ceased to exist as an independent state for over a century

During World War II, Poland was invaded and occupied by Nazi Germany, resulting in the deaths of over six million Polish citizens, including three million Jews who were murdered in the Holocaust. Following the war, Poland became a satellite state of the Soviet Union and was occupied by Soviet forces until the fall of the Soviet Union in 1989.

Throughout its history, Poland has also been invaded by other powers, including the Mongols, Teutonic Knights, and Ottoman Empire, among others. The country's location in central Europe, as well as its fertile land and valuable resources, have made it a target for invasion throughout history.

Overall, while there is no definitive answer to which country has been the most invaded in history, Poland's history of being invaded and occupied by numerous neighboring powers makes it a strong contender for this title.
