Baekje was ancient kingdom on the Korean Peninsula from 18 BCE to 660 CE. Baekje was also called Nam Buyeo. According to the Samguk Sagi, a historical record published in ancient Korea, Baekje was founded by Onjo at Wirye-sung (the present-day Han River area in Seoul). Baekje was one of the three kingdoms of Korea together with Goguryeo and Silla. Beakje, Goguryeo and Silla tried to expand each of their lands by allying and making war against one another.
In the 4th century, Beakje conquered almost every southern part of the Korean Peninsula and flourished by accepting Buddhism and reforming its system. Also, due to its advantageous natural environment, Baekje easily traded with China and Japan. Especially Baekje established goodwill relationships with Japanese rulers of the Kufun period and transmitted its advanced culture such as pottery and Buddhism to Japan.
However, in the 5th century, Baekje was defeated by Goguryeo. It suffered the loss of its capital. Baekje moved its capital to Ungjin. In 6th century, King Seong decided to move capital to Sabi to restore Baekje's glorious past. However, Baekje was ruined by Silla at 660. Although Baekje was destroyed at that time, many ill-fated attempts were existed to restore Baekje from its descendants.
App Store (iOS)
The App Store is an online market used on Apple's iOS, managed by Apple Inc. The App Store lets users view and download applications that were made with the iOS Software Development Kit. Apps can be downloaded onto an iOS device directly, or onto a computer using iTunes (also managed by Apple).
Apps in the App Store are made mainly for iOS devices, such as iPhones and iPads. Some apps can be downloaded for free while others have a cost. Some have "in-app purchases", which are purchases made within the app. These are sometimes done to remove ads or to add features to an app. 30% of all profit made through apps goes to Apple, while 70% goes to whoever made the app.
