Book excerpt: Colombia is the fourth largest country in South America and one of the continent's most populous nations. It has substantial oil reserves and is a major producer of gold, silver, emeralds, platinum, and coal, along with a significant number of natural resources. Colombia has also been ravaged by a decades-long violent conflict involving outlawed armed groups, drug cartels, and gross violations of human rights. Recently the country has made some progress towards improving security, and President Santos has pledged to continue to improve security by passing laws to strengthen the judicial system; a reform of the manner of distributing royalties paid by mining and petroleum companies; and a tougher law against corruption. The Historical Dictionary of Colombia covers the history of Colombia through a chronology, an introductory essay, appendixes, and a bibliography. The dictionary section has over 1,000 cross-referenced entries on important personalities, politics, economy, foreign relations, religion, and culture. This book is an excellent access point for students, researchers, and anyone wanting to know more about Colombia.
