Final answer:
The Russian alphabet, also known as Cyrillic, was derived from the Greek alphabet by Byzantine missionaries Saints Cyril and Methodius during the 9th century. It was created to translate biblical scriptures into Slavic languages, and it eventually became widely adopted by Slavic countries, including Russia.
Step-by-step explanation:
The Russian alphabet, also known as Cyrillic, is a writing system used for the Russian language. It was derived from the Greek alphabet during the 9th century by two Byzantine missionaries, Saints Cyril and Methodius. These missionaries were sent to the Slavic tribes to spread Christianity and also developed the Glagolitic alphabet, which eventually evolved into the Cyrillic alphabet.
The Cyrillic alphabet was created to help translate biblical scriptures into the Slavic languages. It was based on the Greek alphabet, but additional letters were added to represent sounds specific to Slavic languages. Over time, the Cyrillic alphabet became widely adopted by Slavic countries, including Russia. Today, it is used in several countries as the official writing system.
