What is "future in the past"?

When we talk about the past and refer to something that was going to happen in the future at that past point, we use special structures. These are the "past" forms of normal future expressions.

"She was going to call, but she forgot." (= she planned to call; past of "going to")
"He would later become president." (= this is what happened in his future; past of "will")
