Which dynasty's period ended in 1909 AD?

• A. Koryo Dynasty
• B. Chosun Dynasty
• C. New Silla Dynasty
• D. Koguryo Dynasty

Answer: (B)

The question tests your ability to place these dynasties on a timeline and see which one reaches into the late 19th/early 20th century. Among the options, only the Chosun (Joseon) Dynasty lasts into the late medieval-to-early modern period. Joseon began in 1392 and continued into the late 1800s, undergoing a transition in 1897 when Korea became the Korean Empire, and the monarchy effectively ended with annexation in 1910. The other dynasties ended centuries earlier—Koguryo by 668, New Silla by around 935, and Koryo by 1392—so they cannot be tied to an end date of 1909. Therefore, the Chosun Dynasty is the one whose period is aligned with ending around that time.
