example, the rebellion of Sheikh Ubeydullah in Turkish Kurdistan around 1880 inspired Simko Shikak to rebel in 1918, while the various Barzani rebellions in Iraqi Kurdistan became a source of support for the Republic of Mahabad. Other examples of cross-border interaction include the subjugation of the Simko Shikak revolt forcing Simko to flee to Rawandiz in Iraqi Kurdistan – where he sought the support of Sheikh Mahmud Barzanji. Following the fall of the Republic of Mahabad in 1946, some of its leaders also fled to Iraqi Kurdistan where they were sheltered by the son of Sheikh Mahmud Barzanji. Mustafa Barzani had also supported the Republic of Mahabad by sending 2,100 soldiers which in turn also increased Kurdish self-confidence. Many teachers and military officers from Iraqi Kurdistan moreover crossed the border to support the republic. In 1944, the Society for the Revival of the Kurds/Kurdistan (JK) considered the first Kurdish nationalist movement met with a Turkish Kurdish delegation and an Iraqi Kurdish delegation at the border area near Mount Dalanpar where they signed the Pact of Three Borders which demonstrated the existence of a strong Kurdish sense of cross-border solidarity and sentiment. Cross-border interaction became difficult to sustain in the 1950s due to repression from SAVAK on the Iranian side. However, Kurds were able to reinforce the cross-border political activity, when the First Iraqi–Kurdish War commenced in 1961, as the Democratic Party of Iranian Kurdistan (KDPI) gave financial support and loyalty to their counterpart in Iraq, the Kurdistan Democratic Party (KDP), while KDPI themselves accessed spatial resources. Relations between KDP and KDPI would later deteriorate greatly as KDP became a close ally of SAVAK against Iraq. CIA documents from 1963 show that the KDP rebuffed support from KDPI due to the desire to maintain close relations with Iran. In the 1970s, KDPI with Komalah and the Patriotic Union of Kurdistan (PUK) fought around Piranshahr, Sardasht, Baneh in the northern parts of Iranian Kurdistan against Iranian forces who received support from KDP. Cross-border interaction after 1979 After the Iranian Revolution in 1979, political infighting among Kurds increased and KDPI and Komala fought over political and spatial influence in Iranian Kurdistan as they were fighting Iran together. In the 1980s, the two political and military groups had become powerful and cross-border interaction was therefore less important.
