No. Law school admission is based on (in order of importance): 1) GPA in a rigorous course of study (e.g., History), 2) LSAT scores, 3) personal statement, 4) letters of reference, and 5) other activities. By doing well in History or another rigorous program that requires copious reading, writing, and critical analysis of sources, regardless of concentration, you increase your chances of gaining admission. For those who are admitted to law school, the study of History equips students with the most important skills for success in law school—close reading of sources, critical analysis, and clear writing—at least as well as any course of study and better than many.
