At the time of the 2006 National Census, the city's population was 91,664 in 22,440 households.[7] The following census in 2011 counted 110,464 people in 29,743 households.[8] The 2016 census measured the population of the city as 136,654 people in 39,368 households.[2]
The archaeological site of Tepe Qaleh Naneh is located in the Marivan plain near the city of Marivan. It is a large site that extends to the south and around the modern city.
Lake Zaribar is roughly at the centre of the Marivan plain. The settlement of Qaleh Naneh goes back to the Late Chalcolithic period. During that time, this already became a complex society, and had extensive cultural and commercial links with the neighbouring regions.[10]
A joint Italo-Iranian project, ‘Qaleh Naneh: Text Excavations and Survey in the Marivan Valley’ (QaNaTES), is now conducting the scientific investigations in this region of Marivan. It is focusing on the area of the Lake Zarībār and the valley of Marivan, and their development during the Bronze and Iron Ages (ca. 3000-600 BCE).[11]
The region of Qaleh Naneh is mentioned in cuneiform texts from the time of Amar-Sin (c. 2046–2037 BC), the third ruler of the Ur III Dynasty. A series of ancient place-names is known, that referred to journeys along the mountain roads between Qaleh Naneh area and the Tanjero river valley in Iraq.[12]
So this area has long time cultural and trade connections to the Diyala valley in Iraq. Especially the area around the modern Iraqi city of Halabja is relevant. That's where the Tanjero river joins Sirwan river and together they form the Diyala valley. Traditionally, the Diyala valley provided an important trade route between Iran and Iraq.[13]
At the time of Ashurnasirpal II (883-859 BC), the plain of Marivan belonged to 'the region of Zamua', that was probably politically autonomous.
Some ancient texts also refer to 'a sea of Zamua'. There has been considerable confusion in past scholarship about this location. Although Assyriologist Adolf Billerbeck (1834-1908)[14] identified it with Lake Zaribar as early as 1898, other scholars also preferred to identify it with the much bigger Lake Urmia, that is also located in Iran, but a very considerable distance (about 250km) directly to the north of Zaribar.[15]
