Bahrain’s relationship with Qatar is long-standing. After the Al Khalifa conquered Bahrain in 1783 from their base in Qatar, Bahrain became the Al Khalifa seat. Subsequently, tribal elements remaining in Qatar sought to assert their autonomy from the Al Khalifa. Thus, in the early nineteenth century, Qatar was the scene of several conflicts involving the Al Khalifa and their rivals, the Al Thani, as well as various outsiders, including Iranians, Omanis, Wahhabis, and Ottomans. When the British East India Company in 1820 signed the General Treaty of Peace with the shaykhs of the area designed to end piracy, the treaty considered Qatar a dependency of Bahrain.
