Why did Enver Hoxha break alliances with Yugoslavia, the Soviet Union, and China?

Enver Hoxha, the leader of communist Albania, maintained a policy of breaking alliances with major powers when he perceived them as threats to his personal authority, the sovereignty of Albania, or the ideological purity of his regime.1

• Yugoslavia (1948): Hoxha broke relations with Yugoslavia due to his strong nationalist stance and opposition to Yugoslav plans for a federation that would have absorbed Albania into a Belgrade-dominated state.123
• Soviet Union (1961): Following the death of Joseph Stalin, whom Hoxha deeply admired, relations with the Soviet Union deteriorated under Nikita Khrushchev. Hoxha became disillusioned with Moscow, particularly after Khrushchev’s 1955 rapprochement with Yugoslavia’s Josip Broz Tito. Hoxha accused the Soviet leadership of abandoning Marxism-Leninism for the sake of rapprochement with the capitalist West.124
• China (1978): After breaking with the Soviets, Albania forged close ties with China. However, this alliance ended following the death of Mao Zedong and China’s subsequent move toward rapprochement with the West, which Hoxha viewed as a betrayal of socialist principles.14

Following these ruptures, Hoxha adopted a "go-it-alone" policy, isolating Albania as a bastion of Stalinism.4
