Why is Everyone Named Kim, Lee, or Park?
The History and Secret of Korean Surnames
schedule 5 min read
If you meet a group of Koreans, there is a statistically massive chance that at least one of them will have the last name Kim. Walk into any room in South Korea, call out "Mr. Lee!" or "Ms. Park!", and multiple people will turn their heads.
In fact, Kim (김), Lee (이), and Park (박) make up nearly 50% of the entire South Korean population. But why? Is half the country related to each other? The answer lies in a fascinating mix of ancient royal history and an 19th-century social revolution.
1. The Royal Bloodlines: Kings and Aristocrats
For thousands of years during the ancient kingdoms of Silla, Goguryeo, and Baekje, surnames were a luxury strictly reserved for the king and the highest-ranking nobility. Commoners and slaves simply had first names.
The names Kim (meaning "Gold") and Park were the royal surnames of the Silla Dynasty (which unified the Korean peninsula). Later, the name Lee (meaning "Plum tree") became the royal surname of the Joseon Dynasty, which ruled Korea for 500 years until 1897.
2. The 19th Century "Surname Boom"
During the late Joseon Dynasty, the strict class system began to collapse. Wealthy merchants who were technically commoners started buying "Jokbo" (genealogical records) from bankrupt aristocratic families. Naturally, they bought the most prestigious names they could find: the royal names of Kim, Lee, and Park.
In 1894, the class system was officially abolished, and a few years later, a new law required every citizen to register a surname. Given the choice, the vast majority of commoners and freed slaves simply adopted the surname of their former master, or they picked the most elite, famous royal names available.

3. The Secret of the Clans (Bon-gwan)
So, are all Kims related? No!
Because so many people share the same surname, Koreans use a system called Bon-gwan (본관), which means "clan" or "ancestral hometown." Your surname is actually tied to a specific geographic origin.
For example, there are the Gimhae Kims (descendants of the royal house of Gaya), the Gyeongju Kims (descendants of the Silla kings), and the Andong Kims. Even though they are all named Kim, they belong to completely different family trees and are not considered relatives.
