Women eventually won the right to vote in many countries and own property and receive equal treatment by the law, and these changes had profound impacts on the relationships between men and women. In many societies, individuals could decide—on their own—whether they should marry, whom they should marry, and when they should marry.
A few centuries ago, dating was sometimes described as a "courtship ritual where young women entertained gentleman callers, usually in the home, under the watchful eye of a chaperone," but increasingly, in many Western countries, it became a self-initiated activity with two young people going out as a couple in public together.
Today, the institution of dating continues to evolve at a rapid rate with new possibilities and choices opening up particularly through online dating.
The word "dating" entered the American language during the Roaring Twenties.
Thus, the concept of marriage is changing widely in many countries.
