The Qatari-Bahraini War (Arabic: الحرب القطرية البحرينية), also known as the Qatari War of Independence (Arabic: حرب الاستقلال القطرية), was an armed conflict that took place between 1867 and 1868 in the Arabian Gulf. The conflict pitted Bahrain and Abu Dhabi against Qatar. The conflict was the most flagrant violation of the 1835 maritime truce, requiring British intervention. The two emirates agreed to a truce, mediated by the United Kingdom, which led to Britain recognizing the Al-Thani family of Qatar as the semi-independent ruler of Qatar. The conflict resulted in wide-scale destruction in both emirates.
