In fact...
In fact, he adopted an aggressive practice against the commands of the Holy Qur’an and Sunnah. A clear example of the same is the case of Ziyad bin Sumayyah. However, to decide whether he was successful in his manipulations or that Imam Hasan (as) did not get anything, will be premature!
As far as the aims and objective of Muawiya are concerned, the analysis by the researchers shows that his ultimate aim was not to defeat Imam Hasan (as) in the battlefield, because if he had been martyred, Muawiya would have only achieved political leadership and his rule would not be considered legal and in accordance with Shariah.
[^3] His real aim was to get a legal status for his government which was possible if Imam Hasan (as) abdicated in his favour and, through the peace treaty, gave him the right to rule. For this reason, he was offering peace from the beginning and was frightening the Iraqis with the consequences of war.
When, through disorder, the internal conditions in his own army became apparent and it was most difficult for Imam Al-Mujtaba (as) to continue the war, then he agreed for peace with Muawiya, but he was only willing to allow him the right to rule in accordance with the terms of the treaty.
There was wide disagreement between the two sides about the terms and conditions of the peace treaty, but when Imam Al-Mujtaba (as) refused to agree to peace under unreasonable conditions, then Muawiya had to agree to all the terms and conditions proposed by the Imam (as) and the treaty was signed accordingly. Muawiya had thought that he would overcome the will of the Imam (as) through power, money and military strength, like he had managed with the Iraqi army personnel and the landlords of Kufa.
The Syrian army had made a show of strength and Muawiya put full political pressure on the Imam (as) that he should formally accept Muawiya as a caliph, but the Imam (as) not only did not accept him as a caliph. But rather called him an oppressive ruler and one who was after power at any cost and who had considered enjoying the pleasures of the world as the ultimate aim of his brief life.
Due to the will power and extreme determination of the grandson of the Holy Prophet (saw), which Muawiya could not visualize earlier, he had to accept the condition that he was only a monarch and not a caliph.
