How Russia humiliated the Ottoman Empire over and over again

The Russo-Turkish wars (or Russo-Ottoman wars) were a series of twelve wars fought between the Russian Empire and the Ottoman Empire between the 16th and 20th centuries. It was one of the longest series of military conflicts in European history. The conflicts ended disastrously for the stagnating Ottoman Empire; conversely, they showcased the ascendancy of Russia as a European power after the modernization efforts of Peter the Great in the early 18th century.
