Shortly after Andronikos was imprisoned, John V sold Tenedos to the Venetians on similar terms to previous failed agreement. The Genoese however did not take kindly to the island being in the hands of the Venetians, with whom they were embroiled in a war. Thus, in 1376, the Genoese, based in their colony in Galata, helped free Andronikos and procure Ottoman troops for him.[4] Andronikos assumed control of Constantinople and imprisoned the Emperor John V and his younger brother Manuel.
