It's the timeline of the SCiLL itself...
There had been discussion of creating a "conservative center" at Carolina for a number of years, led by conservatives in NC (in the NCGA, on the UNC BoT, and those who help direct such efforts from behind the scenes). The consultants who were brought in to advise how to do this cautioned against calling it a "conservative center" and instead advised expressing that it "expanded" the ideological offerings of the university.
The creation of the school was achieved by passed motion by the BOT in an atypical manner in January 2023.
The initial interim Dean and faculty were announced in October 2023, all pulled from existing UNC faculty. These faculty had a fairly broad background, judged as a whole, and provided support for the idea that the school wasn't a "conservative center".
Jed Atkins was named as first full-time Dean of SCiLL in March 2024. Atkins is well-known and well-considered in conservative academic circles. After Atkins was named Dean, most of the initial faculty of SCiLL left the department over the next few months.
Under Atkins, 11 new faculty were named in August 2024. All have ties to conservative academic groups and are consistent with the known-but-denied mission of SCiLL to be a "conservative center".
The BoT, under the direction of the NCGA, were quite successful at creating a "conservative center" on campus, as was the design of SCiLL. Their initial appointments of those who weren't aligned with the actual mission was nothing more than PR whitewashing of the purpose of the center and was remedied quickly once permanent faculty were hired.
