In 1905 the Province of Alberta was formed out of the former Districts of Athabaska (in part) and Alberta. It was, therefore, named in Honour of the Princess Louise Caroline Alberta, daughter of Queen Victoria and wife of the Marquis of Lorne, who had been Governor-General of Canada from 1878-’83. Two years after the creation of this Province by the Dominion government the folowing arms were assigned by Royal Warrant on 30th May, 1907:
Azure, in front of a range of snow mountains Proper a range of hills Vert, in base a wheat field surmounted by a prairie both also proper, on a chief Argent a St. George’s Cross.
As with Manitoba, the Hudson’s Bay Company had for a long period execised vice-regal powers in, at least, a part of that area out of which the new Province was founded.
The arms of the Hudson Bay Company, incorporated by King Charles II in 1670 were:
Ar. a cross gu. between four beavers pass. Ppr. Crest – On a chapeau gu, turned up erm. a squirrel sejant ppr.. Supporters – Two bucks ppr. Motto – pro pelle cutem.
and so, appropiately enough, one finds the principal charge of the arms borne by that Company placed in chief: the Cross of St. George. 
In 1980, on Alberta’s 75th anniversary, a crest and supporters were added to the shield to form the present coat of arms. The crest consists of a beaver, a symbol of the fur trade that led to the exploration and settlement of Canada, with the royal crown on its back. The supporters, a lion (or golden lion) on the left and a pronghorn antelope (Antilocapra americana - Antilocapridae) on the right, stand for Britain and Alberta respectively. Below them is a grassy mount dotted with wild roses. The motto at the base reads FORTIS ET LIBER, Latin for “strong and free.”
