Arizona State Coat of Arms

The coat of arms appears on official state documents, government buildings, and public seals across Arizona. It shares the same design as the state seal, which was drafted at the Arizona Constitutional Convention in 1910 and adopted at statehood.

The design shows a miner with a pick and shovel on the right, a rancher with cattle on the left, and a desert valley with a reservoir and irrigated fields behind them. Mountain peaks and a rising sun fill the background. The motto Ditat Deus runs along the bottom.

The design does not use a divided shield, supporting animals, or decorative crest. It is a picture of the land and the people working it.

Arizona had been a U.S. territory since 1863, but Congress delayed statehood for decades. When Arizona's Constitutional Convention finally met in Phoenix in 1910, delegates designed the full set of state symbols: constitution, motto, and emblem, two years before admission was approved by Congress.

The motto Ditat Deus had already been in use since 1864, when Arizona was still a territory. The convention carried it forward unchanged into the new state's coat of arms. By statehood, that motto had been part of Arizona's identity for 48 years.

The three industries in the design reflected exactly what was happening in Arizona at that moment. Copper mines in the south and east were producing more copper than anywhere else in the country. Cattle ranching had spread across the high desert after the railroads arrived in the 1880s. And Roosevelt Dam, the largest stone dam in the world at the time, had just been completed in 1911, turning the Salt River Valley into farmland.

The design was made official on February 14, 1912, when Arizona was admitted as the 48th and last of the contiguous states.

The Arizona coat of arms organizes its imagery in three layers: workers in the foreground, farmland and water in the middle, and mountains with a rising sun at the back. Every element represents something real that was happening in Arizona in 1912.

The coat of arms was designed to answer one question: what is Arizona? The answer is three industries. A miner, a rancher, and irrigated farmland tell you everything that built the state in 1912. No historical figures, no mythological symbols, no reference to politics. Just work and land.

The rising sun over the mountains adds something the workers alone cannot say. Arizona was last. Every other contiguous territory had already become a state. When Arizona entered the Union on February 14, 1912, the sun rising in its coat of arms carried real weight: this was a beginning, at the end of a long wait.

The motto Ditat Deus ties it together. The copper, the cattle, the river water: none of it was created by the people on the emblem. They found it, used it, and built a state from it. The coat of arms is an acknowledgment of that, and a statement that Arizona intended to keep doing it.

Arizona's current coat of arms grew out of territorial seal designs rather than from an older state coat of arms. Wikimedia Commons preserves two useful territorial predecessors that show how Arizona's official emblem changed before statehood.

The 1912 state design kept the territorial motto Ditat Deus but replaced the deer-and-cactus territorial imagery with the miner, rancher, reservoir, and mountain sunrise scene adopted at the Constitutional Convention.
