The book is divided into nine parts, each one corresponding to a historical period or theme. The first part deals with the pre-Hispanic civilizations that inhabited the Bolivian territory, such as Tiwanaku, Wari, Chiripa, Mollo and Inca. The second part covers the colonial era, from the arrival of the Spanish conquistadors to the independence movements of the early nineteenth century. The third part focuses on the formation and consolidation of the Bolivian republic, from its foundation in 1825 to the War of the Pacific in 1879-1884. The fourth part examines the economic, social and political transformations that took place in Bolivia during the late nineteenth and early twentieth centuries, such as the rise of tin mining, the Liberal Revolution of 1899, the Chaco War of 1932-1935 and the emergence of nationalism and populism. The fifth part analyzes the revolutionary period of 1952-1982, marked by the National Revolution of 1952, the agrarian reform, the nationalization of mines, the military coups and dictatorships, and the struggles for democracy and human rights. The sixth part studies the democratic transition and consolidation that began in 1982 and lasted until 2005, highlighting the challenges and achievements of different governments and social actors in terms of economic stabilization, political participation, decentralization, constitutional reform and social inclusion. The seventh part explores the period of 2006-2015, characterized by the rise to power of Evo Morales and his Movement for Socialism (MAS), the adoption of a new constitution that proclaimed Bolivia as a plurinational state, the implementation of policies aimed at reducing poverty and inequality, promoting indigenous rights and sovereignty over natural resources, and facing conflicts with opposition groups and regional movements. The eighth part provides a statistical overview of Bolivia's demography, economy and society, with tables, graphs and maps that illustrate key indicators and trends. The ninth part offers a biographical dictionary of prominent figures in Bolivian history, from political leaders to cultural icons.
