Mexico Grande is a timeline, in which Mexico instead of the United States became a superpower.
- Early 1770s, King George III, appoints a "Governor General of British North America" and convenes the Continental Congress. In a proclamation he states that North America will eventually be given autonomy and representation in the British Parliament.

- 1795, the United States allies with Napoleon's France and the war resumes. At some point the United States controls most densely populated areas of British North America.
- 1812, after the United States suffer several major defeats, new ceasefire agreement is signed. The United Kingdom finally recognises the independence of the United States. A boundary of is defined: Massachusetts goes to the United States, and the Upper New York (later known as New Yorkshire) to the British North America.
- 1815, after Napoleon is defeated, Louisiana refuses to recognise the Bourbon monarchy and proclaims independence.
- 1816, the treaty of alliance between Louisiana and the United States is signed. In the next years Louisiana becomes flooded with emigrants from France and colonists from the United States.
- 1836, after the Texas revolution, Texas proclaims its independence from Mexico as the Republic of Texas.
- 1842, Texas is invaded by Mexico. To avoid forced incorporation into Mexico, Texas joins the alliance treaty and along with Louisiana becomes United States' allied republic. With the United States' help, Texas retains its independence from Mexico.
- 1843, after the war with Texas and the United States is lost, Santa Anna's government is overthrown in Mexico, and the Federal Republic of Mexico is proclaimed. It becomes a catalyst for a new era of reforms.

In response to the Southern-States-dominated government's attempts to centralise the country and to effectively legalise slavery in all the territory of the United States, the Northern States declare their secession from the union, and formation of a new nation: the Free States of America. The union army wins several battles, but when the Free States threatens that it will ask for British protection the Southern government is forced to sign ceasefire agreement.
- 1861, Mexico invades Central America. The armies of Guatemala, Honduras and El Salvador are defeated, but Mexico fails to organize effective control over the territory. Eventually Guatemala becomes the only Central American country to be annexed by Mexico.
