When Mohammed Daoud Khan ousted the monarchy, and established the Republic of Afghanistan, the Khalqist PDPA offered its support for the new regime if it established a National Front which presumably included the Khalqist PDPA itself. The Parchamite PDPA had already established an alliance with Daoud at the beginning of his regime, and Karmal called for the dissolution of the Khalqist PDPA. Karmal's call for dissolution only worsened relations between the Khalqist and Parchamite PDPA. However, Taraki and Amin were lucky; Karmal's alliance actually hurt the Parchamites' standing in Afghan politics. Some communists in the armed forces became disillusioned with the government of Daoud, and turned to the Khalqist PDPA because of its apparent independence. Parchamite association with the Daoud government indirectly led to the Khalqist-led PDPA coup of 1978, popularly referred to as the Saur Revolution. From 1973 until the 1978 coup, Amin was responsible for organising party work in the Afghan armed forces. According to the official version, Amin "met patriotic liaison officers day or night, in the desert or the mountains, in the fields or the forests, enlightening them on the basis of the principles of the working class ideology." Amin's success in recruiting military officers lay in the fact that Daoud "betrayed the left" soon after taking power. When Amin began recruiting military officers for the PDPA, it was not difficult for him to find disgruntled military officers. In the meantime, relations between the Parchamite and Khalqist PDPA deteriorated; in 1973 it was rumoured that Major Zia Mohammadzai, a Parchamite and head of the Republican Guard, planned to assassinate the entire Khalqist leadership. The plan, if true, failed because the Khalqists found out about it.
