Baroque architecture is a highly decorative and theatrical style which appeared in Italy in the early 17th century and gradually spread across Europe. It was originally introduced by the Catholic Church, particularly by the Jesuits, as a means to combat the Reformation and the Protestant church with a new architecture that inspired surprise and awe. It reached its peak in the High Baroque (1625–1675), when it was used in churches and palaces in Italy, Spain, Portugal, France, Bavaria and Austria. In the Late Baroque period (1675–1750), it reached as far as Russia, the Ottoman Empire and the Spanish and Portuguese colonies in Latin America. In about 1730, an even more elaborately decorative variant called Rococo appeared and flourished in Central Europe.

Ottoman Baroque architecture, also known as Turkish Baroque, was a period in Ottoman architecture in the 18th century and early 19th century which was influenced by European Baroque architecture. Preceded by the changes of the Tulip Period and Tulip Period architecture, the style marked a significant departure from the classical style of Ottoman architecture and introduced new decorative forms to mostly traditional Ottoman building types. It emerged in the 1740s during the reign of Mahmud I (1730–1754) and its most important early monument was the Nuruosmaniye Mosque, completed in 1755. Later in the 18th century, new building types were also introduced based on European influences. The last fully Baroque monuments, such as the Nusretiye Mosque, were built by Mahmud II in the early 19th century, but during this period new European-influenced styles were introduced and supplanted the Baroque.
