Question: In the early Heian period, the late 8th and early 9th centuries, Emperor Kammu sought to consolidate and expand his rule in northern Honshu, but the armies he sent to conquer the rebellious Emishi people lacked motivation and discipline, and failed in their task.[citation needed] Emperor Kammu introduced the title of sei'i-taishogun () or Shogun, and began to rely on the powerful regional clans to conquer the Emishi. Skilled in mounted combat and archery (kyudo), these clan warriors became the Emperor's preferred tool for putting down rebellions.[citation needed] Though this is the first known use of the "Shogun" title, it was a temporary title, and was not imbued with political power until the 13th century. At this time (the 7th to 9th century) the Imperial Court officials considered them merely a military section under the control of the Imperial Court.
Is there an answer to this question: In what period did Emperor Kammu rule?

Answer: early Heian period

Question: At the time the store was introduced, purchased audio files used the AAC format with added encryption, based on the FairPlay DRM system. Up to five authorized computers and an unlimited number of iPods could play the files. Burning the files with iTunes as an audio CD, then re-importing would create music files without the DRM. The DRM could also be removed using third-party software. However, in a deal with Apple, EMI began selling DRM-free, higher-quality songs on the iTunes Stores, in a category called "iTunes Plus." While individual songs were made available at a cost of US$1.29, 30 more than the cost of a regular DRM song, entire albums were available for the same price, US$9.99, as DRM encoded albums. On October 17, 2007, Apple lowered the cost of individual iTunes Plus songs to US$0.99 per song, the same as DRM encoded tracks. On January 6, 2009, Apple announced that DRM has been removed from 80% of the music catalog, and that it would be removed from all music by April 2009.
Is there an answer to this question: When did Apple reveal that most of the iTunes selection was free from DRM?

Answer: January 6, 2009
