This book profiles Taiwan's six key presidents - namely Chiang Kai-shek, Chiang Ching-kuo, Lee Teng-hui, Chen Shui-bian, Ma Ying-jeou, and Tsai Ing-wen - focusing on politics, economics, elections, successes and failures in office, popularity and democratization.By analysing criteria of the six Presidents' leaderships such as management of crises, advancing democracy, stewardship of the economy, charisma, corruption and handling of foreign relations, especially with China and the US, John F. Copper goes on to rank the presidents and predicts trends and difficulties future presidents will face. Special attention is paid to relations with the US, acknowledging the US as Taiwan's political and economic model as well as it being Taiwan's protector in the context of China's claim to Taiwan.As an assessment of these six political leaders, as well as a study of Taiwan's political system, this book will appeal to students and scholars of Taiwan, political science and international relations.
