Why the Left Hand? ?

• Ancient Roman Belief: The Romans believed in the Vena Amoris ("Vein of Love"), a vein that supposedly ran from the left ring finger to the heart. This idea influenced many Western cultures, including the U.S., France, Italy, and the UK.
• Catholic Protestant Influence: Many Catholic-majority countries, such as France, Portugal, and Ireland, adopted this tradition.
• Western Popular Culture: Hollywood and Western engagement traditions reinforced the left-hand practice.

Why the Right Hand? ?

• Biblical Religious Symbolism: Some Christian traditions view the right hand as the “hand of God” (e.g., the Bible refers to Jesus sitting at the right hand of God). This influenced Orthodox Christian and Protestant-majority countries like Germany, Austria, Poland, and Greece.
• Practical Reasons: In some cultures, the right hand was traditionally seen as the stronger, more dominant hand, making it a more important symbolic choice for marriage.
• Historical Traditions:
  • In Germany and the Netherlands, engagement rings are worn on the left hand and then moved to the right hand after marriage.
  • In Spain, regions like Catalonia and Valencia wear wedding rings on the left, while other areas prefer the right.
