The event cost £10million. It was a king's ransom but the city's fathers thought it was worth every penny because it helped highlight Glasgow as one of the world's power houses.
The British Empire was at the height of its strength and influence across the globe.
At the time it covered a quarter of the world's land mass and controlled a quarter of the global population.
Glasgow was chosen to showcase the empire's architecture and design.
It was also an opportunity to highlight Scotland's culture and industry.
The exhibition was spread over 175 acres at Bellahouston Park - five times the size of Hampden Park.
