The 2006 removal of Prime Minister Thaksin Shinawatra spurred widespread protests over the next several years and resulted in mass demonstrations in 2010 and 2011.
A year later, his sister Yingluck was installed as the country's new caretaker leader, but her tenure was plagued by allegations of her brother's involvement -- allegations she strenuously denied.
The situation reached a tipping point in 2013, as demonstrators demanded an end to Shinawatra politics. She was removed from office months later amid allegations of abuse of power.
