Blackening and Kidnapping of the Bride - Marrying a Tree - Interesting marriage customs from around the world
Here are a few examples of unusual or interesting marriage customs from around the world:

1. Blackening of the Bride (Scotland): In some parts of Scotland, friends and family of the bride and groom ambush them and cover them in various messy substances such as mud, flour, and feathers. This tradition is believed to prepare the couple for the challenges of married life.
2. Kidnapping of the Bride (Romania): In certain Romanian communities, friends of the groom may playfully “kidnap” the bride before the wedding ceremony. The groom must then ransom her back with romantic gestures or, more commonly, drinks.
3. Marrying a Tree (India): In some parts of India, particularly in rural areas, there is a tradition known as “Kumbh Vivah,” where a person, usually a woman, is married to a tree first to ward off inauspicious astrological combinations. After the tree marriage, the woman can marry a human without fear of bad luck.
4. Crying Ritual (China): In the Tujia ethnic group in China, brides are expected to cry for an hour every day in the month leading up to the wedding. After ten days, the bride’s mother joins her, and then her grandmother. The women cry in different tones, creating a melodious sound. The custom is believed to be an expression of joy, with the women crying in different styles.
5. Beating the Groom’s Feet (South Korea): In South Korea, during the groom’s first night at his in-laws’ house, family members playfully hold down his feet and lightly beat the soles with sticks or dried fish. This tradition is believed to make the groom more energetic for the wedding night.
6. Shoe Hiding (India – Punjabi Tradition): In Punjabi weddings, the groom’s shoes are often stolen by the bride’s sisters or female relatives. To get his shoes back, the groom is expected to pay a ransom, usually in the form of money or gifts.
7. Tossing the Bouquet and Garter (Western Tradition): In many Western weddings, the bride tosses her bouquet, and the unmarried female guests compete to catch it. Similarly, the groom removes and tosses the bride’s garter, and unmarried male guests attempt to catch it. It’s believed that the person who catches the bouquet or garter will be the next to marry.
These customs, while unconventional to some, are an integral part of the cultural tapestry of different societies and add a unique charm to wedding celebrations around the world.
