In what state was the Crimea after the collapse of the USSR and what prompted it to return to Russia?

In general, Crimea was at the moment when the USSR collapsed, in a normal economic state, because after its transfer to the Ukrainian SSR, all kinds of communications were brought there, the North Crimean canal was built, which supplied the peninsula with fresh water from the Dnieper and allowed the qualitative development of agriculture. In political terms, this location is also convenient, because there was a land connection with mainland Ukraine. It was the fact that many Crimeans did not really consider themselves Ukrainians and had pro-Russian sentiments to move over to the jurisdiction of the Russian Federation; moreover, moments of history were cultivated, that Sevastopol was a city of glory for the Russian navy, and so on.
