It is said that "Mirza Abbas Iravani," known as "Haj Mirza Aghasi," who was the prime minister for 13 years after the murder of Ghaem Magham Farahani during the Qajar era, spent most of his time in Abbasabad and paid special attention to developing this area, which is why the area was named after him. Contemporary historians have written that Abbasabad was a village with a fort, peasant houses, and a manor house that offered ample facilities for Mirza Aghasi's residence and hosting his guests. After his death, Mostowfi ol-Mamalek bought these lands and added them to his other properties, including Yusefabad and Behjatabad.
According to available documents, in 1964, a company named "Abbasabad Hills" was established with a capital of one billion tomans. In 1974, it was decided to build the largest urban complex on these lands. In 1975, a comprehensive plan was developed by a British company, defining various usages such as gardens (Shahestan), administrative, commercial, and cultural complexes with metro access. The project was initiated in 1978 but was not completed.
In 1986, during Ayatollah Khamenei's presidency, a directive recommended using the entire lands for long-term cultural, political, and green space projects. Later, another plan proposed establishing administrative centers in the area. Finally, in 1992, Karbaschi (the then-mayor) transferred the entire lands to the then-president, Ayatollah Hashemi Rafsanjani, who assigned them to government departments and complexes. In 1993, the Supreme Leader issued a letter instructing the entire lands to be converted into cultural use on a national and regional scale, portraying the authentic Iranian-Islamic culture in the capital.
