The Ottoman government is an absolute monarchy that lost contact with people over time. It also lacks inheritance rules, and history shows a lack of political turmoil and power leading to monarch / leader's death. (Other examples - Roman Emperor, Early Muslim Caliphate Prophet, Caliph Muhammad etc) Leaders are Sultan, endorsed by the bureaucrat and endorsed by the Minister. Leaders like Suleiman the Magnificent have expanded the power of the Ottoman Empire through trade advantage; Istanbul is an important trading city in the center of the Ottoman Empire. However, the Ottoman refused because of the inheritance problem, rapid expansion of the border, farmer uprising, and instability caused by economic problems due to war.
Religiously, the Ottoman Empire is very tolerant. The Ottoman Empire is a Sunni Muslim - a Muslim believer. With the Qur'an in mind, Christians and Jews are considered to be people of books and are highly respected, or at least acceptable.
Safavid Empire was formed in modern Iraq, Iran, part of Afghanistan. Like the Ottoman Empire, Safavid expanded to the west with their army. The most famous Shah was Abbas the Great, hired Persians to bureaucrats and organized armies of troops conquered like the Ottoman Empire and their homeless. . Like the Ottoman Empire, Safavid suffered a series of weak leaders, and the domestic struggle to control the empire brought more weakness. After all, Safavids went to the hands of Afghanistan's attackers.
Religiously, the Safavi people are in accordance with the Shi'ites of Islam, unlike the Sunni Ottomans. Religious leaders and teachers will help Muslim spread throughout the empire. They are not as tolerant as non-Shi'a Muslims.
Another major difference between the Ottoman Empire and the Spanish Empire is the religious aspect. The Ottoman Empire is the Islamic Empire and the Spanish Empire is the Christian Empire. The difference in this religion is very important as most governments and societies are managed by religion during this time. If the two empires have different religions, this will also bring some other differences between them. This is because religion is very influential on the government. Because the Ottoman Empire follows Islam, their law is based on the Islamic Code and is called the Islamic law. Laws and regulations covers many topics including crime, politics, economy. Because the Spaniards are Christians, this is different from the Spanish Empire. In other words, the Spanish empire is strongly influenced by the Roman Catholic church. Religion is one of the biggest differences between Spain and the Ottoman Empire.
In the social aspect, the Spanish Empire and the Ottoman Empire are very strict religious empires. Spaniards are strict Catholics (probably generous). Likewise, the Sultan of the Ottoman Empire is a devout Muslim. The Spaniards spread Christianity throughout the United States and converted indigenous peoples into boys ranked highest among the poorest villages by the Ottoman Empire. However, as the Ottoman embraces other religions, the two empires are actually different. The Ottoman embrace other religions because Ottoman Turks can defend themselves from resistance and rebellion by permitting Christians and Jews to practice their religion freely. One of the main differences between the two empires is the reason for their expansion and conquest. The Spanish Empire expanded to further promote trade, the Ottoman Empire expanded its military rule. The financial base is weak and can not benefit from trade, so the attempts by Spain to improve trade have begun to decline.
