Historically, involvement in relationships has been greatly different across the centuries. Traditionally, in the olden days, engagements are normally arranged by families for reasons other than love and affection. However, love-based engagements have since been popularized among Western cultures over the 18th and 19th centuries. The tradition of an engagement ring dates back to the 15th century, and the well-known example of Archduke Maximilian of Austria giving a diamond ring to Mary of Burgundy is Engagements have, over time, become so much a promise of commitment and love that new customs like proposing with a ring only gained popularity during the 20th century.
