The Reach

The Reach is one of the constituent regions of the Seven Kingdoms, and was formerly a sovereign nation known as the Kingdom of the Reach before the Targaryen conquest. Geographically, it is one of the larger regions of the Seven Kingdoms.

The Reach is the most fertile part of Westeros, blessed with vast, blooming fields of crops and flowers, and numerous and well-populated villages and towns; it traditionally helps supply other less fertile parts of the Seven Kingdoms (most notably King's Landing) with grain, fruit, wine and livestock. The Reach is also the most heavily-populated part of Westeros and is one of the richest, though not as rich as the Westerlands, ruled by House Lannister. Due to this, the Tyrells can traditionally field the largest army in the Seven Kingdoms, almost as large as the armies from two of the other populous kingdoms combined. This vast supply of manpower, land, and food production gives the Reach enormous strategic value during the War of the Five Kings.
