The first iteration of STP (Spanning Tree Protocol) was defined in IEEE 802.1d standard. This standard was first published in 1990 and has since been revised several times (latest revision is 802.1Q-2018). 802.3d, 802.11s, and 802.1c are not related to STP, but instead, define standards for Ethernet MAC, wireless mesh networking, and path control respectively.
