(CNN) — One of the world's most well-known tour operators, Thomas Cook offered low-cost package holidays to dozens of destinations worldwide, making it a popular option for travelers in search of an affordable getaway.
But the Sunday collapse of this 178-year-old UK brand marks the end for one of the oldest travel firms on the planet, a company that's credited with changing the global tourism landscape.
Launched by cabinet-maker Thomas Cook in Leicestershire in 1841, the business originally focused on one-day rail excursions. Cook believed alcohol was to blame for social problems, and organized a special train to carry temperance supporters to a meeting 12 miles away, according to the Thomas Cook website.
In the following years, Cook continued to arrange railway trips for temperance societies and Sunday schools until the summer of 1845, when he organized his first commercial venture -- a trip to Liverpool.
He eventually moved beyond the UK into Europe and then further afield. Over the many decades to follow, the company expanded into hotels, resorts, cruises and airlines, to name just a few of its endeavors, targeting Britain's middle class.
The brand became a household name, along with its tagline: "Don't just book it -- Thomas Cook it!"
Here's a timeline highlighting a few key moments in its history:
