شیروان‌شاهان was a dynasty that ruled over the region of Shirvan in present-day Azerbaijan from the 9th to the 16th centuries. This dynasty is known for its contributions to Persian culture, architecture, and literature. The rulers of شیروان‌شاهان were influential in promoting Islam and played a significant role in the political landscape of the Caucasus. The most notable achievement of شیروان‌شاهان was the construction of the Shirvanshah Palace in Baku, which is a UNESCO World Heritage site today. This palace complex reflects the architectural style of the time and serves as a testament to the dynasty's power and cultural significance in the region.
