What year did homeschooling start?

There's no single year that marks the beginning of homeschooling. Homeschooling, in various forms, has existed throughout history. However, the modern homeschooling movement, as we largely understand it today, began to gain momentum in the late 1960s and early 1970s in the United States. This was fueled by several factors, including increased dissatisfaction with public schools, the rise of alternative education philosophies, and legal challenges to compulsory attendance laws. So, there's no one "start" year, but that period is generally considered the beginning of the modern homeschooling era.
