The Ottoman Empire rose to power by capturing Constantinople and conquering the Byzantine Empire under Suleiman the Magnificent in the 16th century. It strengthened itself by spending a lot on its army and government, but this also became a weakness in the 18th century when trade declined and taxes increased, oppressing citizens. The Ottoman Empire fell as its exterior trade became very poor and citizens felt overtaxed. The Mughal Empire also rose to power through military strength funded by heavy spending on its army and government in the 16th century. However, it weakened as the British and French conquered India and took control of tax collection, and the Mughals were unable to advance their military against European forces.
