Signoria (supreme governing body) of Venice had recently signed a treaty with the Ottomans and disapproved of any ongoing anti-Ottoman activities. Andreas did make at least one further attempt at recapturing the Morea, becoming involved in a 1485 plot to seize Monemvasia from the Venetians. Travels and sale of the imperial title Andreas left Rome to travel to Moscow once more in 1490, accompanied by Moscow's ambassadors to Rome, Greek brothers Demetrius and Manuel Rhalles. For unknown reasons, Andreas appears to have not been welcome in Moscow, and he instead chose to travel to France, where he was generously received by King Charles VIII, who paid for all of his travel expenses after Andreas gifted him a white falcon. Andreas stayed with the king at Laval and Tours from October to December 1491 and received additional money, amounting to 350 , before he returned to Rome. According to chronicler Gherardi da Volterra, Andreas and Charles spent much time discussing the possibility of a crusade against the Ottomans. In 1492, Andreas was in England, where King Henry VII was not as hospitable as Charles VIII, instructing his treasurer, Lord Dynham, to pay Andreas with an amount he thought appropriate and then give him safe passage out of the country. Andreas's European tour in search for aid for his cause was similar to the one conducted by his grandfather, Emperor Manuel II Palaiologos, who traveled Europe from 1399 to 1402 in the hope of securing aid against the Ottomans. In the 1490s, King Charles VIII of France was actively planning a crusade against the Ottomans, but he was also involved in a struggle to gain control of the Kingdom of Naples in southern Italy. The French Cardinal Raymond Peraudi was passionately devoted to Charles's crusading plans and was against him getting embroiled in Italian politics, believing that war against Naples would prove a fatal diversion from attacking the Ottomans. French soldiers were already marching into northern Italy on their way to Naples when Peraudi, hoping to divert them to the East before the conflict with Naples, began engineering a plan (apparently without the king's knowledge) to give Charles a formal claim on the Byzantine throne. Negotiating with Andreas, Peraudi secured that, in return for Andreas abdicating his titles to the imperial thrones of Constantinople and Trebizond, and the Despotate of Serbia, Andreas would receive 4300 ducats annually (almost 360 ducats a month),
