Aghhamzali is a village in the Iravan uezd of the former Iravan governorate, later in the former Zangibasar (Masis) district, and currently in the Ararat province. It had been within the former Gamarli (Artashat) district until 1937. The provincial centre lies 20 km to the northwest of the town of Gamarli, by the Girkhbulag River, at a height of 855 m above sea level. It was marked on the five-verst map of the Caucasus (348, p.3).

The Armenians were removed to the village from Iran in 1828. Along with the Armenians, the village was inhabited by 232 Azerbaijanis in 1831, 301 in 1873, 273 in 1886, 376 in 1897, 843 in 1904, 927 in 1914 and 516 Azerbaijanis in 1916. In 1918 the Azerbaijanis were deported having been exposed to Armenian massacre. After Soviet power had been established in the present-day Armenian territory, the Azerbaijanis managed to return to their homes. The village was inhabited by 93 Azerbaijanis in 1922, 98 in 1926 and 207 Azerbaijanis in 1931. The Azerbaijanis of the village were deported to Azerbaijan in 1948–1949. At present, the village is inhabited by Armenians.

The toponym was coined on the basis of the word “agha” meaning “nobleman, sayyid, holy” and the Gizilbash ethnonym “Hamzali”.

By the decree of the Presidium of the Supreme Soviet of the Armenian SSR dated 25 May 1967, the village was renamed “Marmarashen” and by decision dated 28 May 1967 was further renamed “Getazat”. According to the law “On the administrative-territorial division of the Republic of Armenia” dated 7 November 1995, it was integrated into the administrative area of the Ararat province.
