The massacre of North America's bison in the 1800s paralleled the persecution of the continent's indigenous people.

Since 2012, Parks Canada has been striving to reintroduce the animals, also known as buffalo, to Banff National Park - the oldest park in the country.

In February, more than 50 indigenous tribes bound together to make their return a reality.

Watch as the bison return to the park.
