What is meant by empire by invitation?

"Empire by invitation" refers to a form of Imperialism where a dominant power expands its influence not through direct conquest, but by being invited in by local leaders or governments seeking support or stability. This often occurs in contexts where local authorities request assistance in dealing with internal or external challenges, such as political instability or military threats. The inviting power then leverages this invitation to establish a presence, often leading to a significant degree of control or influence over the invited area.
