Using maps, compare Europe in 1648 and in 1748:why did they lose, why were they weak, and what happened to Poland?

In 1648 the 3 large states of the Holy Roman Empire, Kingdom of Poland, and the Ottoman Empire all lost a lot of territory. The Holy Roman Empire lost its lands in small chunks at the Peace of Westphalia at the end of the 30 years war. The peace also disintegrated the HRE into small nation-states and therfore they were more easily convinced to join other well off nations a little at a time. For the HRE Prussia was the major gainer, slowly Prussia inherited parts of the HRE and connected them through their new stronger monarchy due to the army. The Kingdom of Poland slowly shrank while the King struggled to keep his lords under control, as well as his diverse people. Peter the Great of Russia ended up getting Poland and the Lithuania area with new and strong Kingdom of Russia. The Ottoman Empire was slowly beaten back and out of Europe as the Emperor of the Ottomans struggled to keep his people united also. Christians and Muslims had their own laws, and cuture was kept, making them even more diverse. All the warring took their tolls, and the Ottmans did not fight with the vigor they once had, and the Austrian Habsburgs with their newly strengthened monarchy were able to beat them back into SE Europe.
