What is a kingdom in a Mormon church?

In the Church of Jesus Christ of Latter-day Saints (the "Mormon" church) a kingdom could refer to a couple things.

First is the Kingdom of God. If someone references 'building the kingdom' or something similar, they are referring to the Kingdom of God. The Bible Dictionary, published by the Church, puts it this way, "Generally speaking, the the kingdom of God on the earth is the Church. It is a preparation for the greater kingdom-the celestial or kingdom of heaven. However, kingdom of heaven is sometimes used in scripture to mean the Church, meaning that the true church on the earth is the path to heaven, and is the kingdom of heaven on earth."

Second, the Kingdoms of Glory. Mormons believe that within heaven there are three 'kingdoms' or degrees. The highest of these is the Celestial Kingdom, followed by the Terrestrial and Telestial Kingdoms. There are different requirements to be admitted into each kingdom.
