Origins and development of authoritarian and single-party states: One-party state is a government where only one party governs the country. Forming another party is forbidden by the ruling party. Some examples from history for the one-party state are the Soviet Union from 1922 to 1991, Italy from 1922 to 1943, under Benito Mussolini, Germany under Hitler from 1933 to 1945. When the governance was really high-handed it was known to be governed by dictators and also known as police states. Some countries like China have more than one party but only one party could have control. The other parties could oppose but did not have any real power. In case of China it is the Communist party of China which has been in control for many years.
When Europe was conquering many Asian countries China was never really conquered. But ‘spheres of influence’ were built by France and Britain as China was backward in many ways. The Qing Dynasty did not have progressive ideas and they were over thrown by the Nationalist Party led by Sun Yat-Sen in 1912. Once monarchy was displaced and parties came to rule the Marxist party took root and the Communist Party led by Mao Zedong took over China after winning the Chinese Civil War fought between 1927 and 1950.
Christopher Columbus landed in Cuba in 1492 and Cuba became the colony of Spain. The natives of Cuba were treated badly and many died of diseases brought by the Africans who had come there as slaves. Cubans revolted against the Spanish after 4 centuries but failed. America conquered Cuba in 1898 but gave its independence in 1902. Though Cuba became independent, they were still controlled by Americans. Their corrupt leader, Fulgencio Batista, who was military leader and then the president of Cuba was supported by Americans. In 1952 Fidel Castro took over Cuba. America tried to remove Castro who then sought help from Russia. Russia set up nuclear weapons in Cuba and this worried the Americans. So it was agreed that America would not interfere with the affairs of Cuba and Russia would remove its nuclear weapons. From then on Cuba went the Russia way, becoming a communist country. However Fidel Castro became the most powerful man and his party was the only party to rule for 5 decades till 2008. After that, his brother Raul Castro took over the Communist Party of Cuba and is in control till date. This is another single party ruled state where noon e can speak against the party or the leader.
