In The War Of The Worlds by HG Wells, Martians invade Earth and Venus.
In Star-Begotten by Wells, Planetarium Club members discuss cosmic rays and Martians before one of their number summarizes and criticizes The War Of The Worlds,
mistakenly attributing it to "'...Conan Doyle, Jules Verne, one of
those fellows...'" (New York, 1975, p. 48), then proposes instead
Martianization of human beings by cosmic rays.
Ransom Trilogy by CS Lewis, a scientist visits Mars and Venus, in the
latter case as the spearhead of a planned demonic invasion. Lewis
parenthetically comments that "...Mr Wells' Martians [are] very unlike
the real Malacandrians..." (Voyage to Venus, London, 1978, p. 7).
In The War Of Two Worlds by Poul Anderson, Martians militarily conquer Earth but are being covertly manipulated by extrasolars.
"Soldier From The Stars" by Anderson, humanoid extrasolars conquer
Earth economically by selling their superior military services to the
highest bidder among Terrestrial governments.
Later, I will add a few more alien invasions but I think that this is a neat progression through Wells, Lewis and Anderson. See here.
