Ottoman art and architecture cannot be pinpointed to a specific date or style, as it occurred throughout the entirety of the Ottoman Empire, which reigned from the 13th to the early 20th Centuries. Broadly speaking, Ottoman art and architecture was a fusion of the Islamic and Byzantine styles. Calligraphy was a hugely important art form for the Ottomans, and was used not only for literature but also to decorate works of art and furniture. Carpet weaving, miniature paintings and high quality jewellery production were all crafts that the Ottomans were famous for. In the latter half of the 16th Century, Ottoman craftsmen produced beautiful ceramic wares, the most well-known being the stunning blue and white Iznik works.
