Liberty: Represented in the upper sinister section of the shield by a cannon in front of a mountain with two crosses on it, referring to the 1810 Battle of Monte de las Cruces, part of the Mexican war for independence.
Work and culture: Represented in the bottom section, which contains elements that refer to the toponym of Mexico, which gave name to the state and the country. Also represented are agriculture and the production of corn. An open book for knowledge is shown, with over it a gear, a sickle, a shovel and a flask, tools of human endeavour.
The shield has a red border with the words "Libertad Trabajo Cultura" and eighteen bees, symbolizing the state's 18 districts. The national coat of arms is shown in a circle at the top.
