Kingdom of the Reach

The Kingdom of the Reach is a vast region of the most fertile lands in Westeros, bordered in the north by the Kingdom of the West and the Blackwater Rush, bordered in the south by the Red Mountains and the Principality of Dorne, bordered to the west by the Sunset Sea, and bordered to the east by the Kingdom of the Storm.

Government
The Kingdom of the Reach is ruled from Highgarden, its overlord House Gardener. They are joined by their hereditary stewards of House Tyrell, the two families ruling the Kingdom ably and well. The Gardeners are popular and generally produce good rulers, and have steadily grown their realm for centuries.

Economy
The Reach is dominant in the field of agriculture-- their farms are, bar none, the most productive in the whole of Westeros. Reach lords grew wealthy and powerful selling their bountiful harvests to neighboring kingdoms. Beyond that, the Reach is bookended by major trade hubs-- Oldtown and Tumbleton. Oldtown merchants grow rich shipping their goods over land to the Mander and up the great river to the latter town, and the two have a good trading relationship.

Notable exports beyond grains are the golden wines produced on the Arbor, renowned around Westeros. Many artisan goods from Oldtown fetch a high price across Westeros, and the Citadel produces many books and scrolls that are circulated around the realm.

Military
The Reach is the dominant military force of Westeros. If the lords of the Reach were to levy their men at once, they could raise upwards of 100,000 men-- more than twice the size of any other kingdom fully levied.

They also boast the largest navy on the west coast of Westeros, courtesy primarily of the Redwyne fleet-- though the Hightowers and the Chesters contribute sizeable contingents to any massed Reachman fleet.

Garth Greenhand
The man most Reachmen trace their lineages to is Garth Greenhand, a legendary king who ruled during the Age of Heroes. The Gardeners of Highgarden trace their lineage to Garth Greenhand, as well, through his firstborn son and heir Garth the Gardener. Garth Greenhand was said to have been progenitor to some other major houses in the Reach, including: House Oakheart, House Redwyne, House Hightower, House Florent, House Ball, House Peake, House Tarly, House Bulwer, House Crane, and House Rowan.

The Gardener Kings
Ruling originally the lands immediately adjacent to the Mander, known as the "Reach Proper." From the Reach Proper the Gardener Kings expanded their realm to include Old Oak, Goldengrove, and Red Lake through a pact of mutual defense against the Kings of the Rock. In the south they expanded to include Oldtown through marriage and the Arbor through a pact against the Ironborn. House Tarly and the western marches came to the Kingdom of the Reach through a war against the Dornish. Much of the western Kingdom of the Storm was conquered by the Kings of the Reach, leading to their odd, long border stretching across the Red Mountains. Additional territories joined the Kingdom through the generations until it reached its present size and strength.

These kings have in general ruled ably and well. They are assisted by the Tyrells, their hereditary stewards, who have at times stepped up to hold the Kingdom of the Reach together.
