In the late 20th century, the study of world history emerged to enable historians and students to understand the world from a global perspective. World history is considered part of the academic field rather than the research field. According to Charles Hedrick, author of The Ethics of World History, Western civilization was the primary course taught in schools and universities before world history became part of the school curriculum. The need to understand the world from a broader perspective than a Western perspective has made the study of world history popular in the United States. Historians have approached the study of world history with a thematic approach to understanding the integration and difference between people and major world events. The subject of world history is vast and, therefore, open to many interpretations. Additionally, world historians have struggled to connect the past while trying to bring in all the perspectives of other cultures. These challenges have made it difficult for historians to agree on a comprehensive framework for understanding world history, without ignoring other cultures. As a result, historians have approached world history differently and developed multiple orientations such as patriotic, Marxist, postcolonial and ecumenical approach in order to meet the criteria. Criticisms have emerged of different approaches to world history. Historians have questioned and criticized the study of world history because the different approaches have resulted in controversial topics such as the use of a Eurocentric perspective on history, questions of ethics and the use of definitions that have changed over time. History is the position taken when looking at history in the middle of a paper......pointing out the flaws it has produced. Over time, controversial issues such as the use of a Eurocentric perspective, questions of ethics, and the use of language would evolve for the better.
