, an ancient mosque in Koyra discovered in the 20th century.|left Koyra's history most likely dates as far back as the office of
Khan Jahan Ali in the 15th century at least. This is evident from the ancient mosques found in Koyra such as
Masjidkur. The Channir Chak L.C. Collegiate School was established in 1935. In 1962, the
Koyra Madinabad Secondary School was established.During the
Bangladesh Liberation War of 1971, a sub-sector of
Sector 9 was founded in Koyra's Amati Union known as Bachharbari-Manoranjan Camp, and so most of the
Mukti Bahini's and
Mujib Bahini's operations were launched from here. The Bengali freedom fighters built five camps in Koyra; World Poet Camp led by Abd al-Latif, Najmul Camp led by KM Mujibur Rahman, Nazrul Camp led by Abd al-Hakim, Narayan Camp led by Keramat Ali, Shaykh Abd al-Jalil and Shamsur Rahman in Jhileghata and the Suhrawardy Camp led by Rezaul Karim in Bamiya, Bagali Union. In Jaygirmahal, Dr Rafiqul Islam ran a secret medical centre to provide treatment to wounded freedom fighters. A mass grave was found in Launch Ghat, Marighata. On 19 November 1979, Korya was established as a
thana. It was upgraded to an upazila (sub-district) on 7 November 1983. The Upazila suffered heavy damage following the
Cyclone Sidr in 2007 and
Cyclone Aila two years after that. == Geography ==
