Source-derived summary

Theta Upsilon (ΘΥ) was a national women's fraternity operating in the United States from February 1921 until May 1962, when the group was absorbed by the Delta Zeta sorority.

History

Local club

Theta Upsilon began as a local club at the University of California, Berkeley when six female students moved into a house on Walnut Street. The house became known as "The Walnut Shell".

In the academic year of 1913–1914, twelve girls organized an official "house club" under the university. It was called Mekatina, which meant "Among the Hills". Mekatina had a ritual based on Native American themes. The pin was a rising sun. The formal founding date, according to Delta Zeta's history, was January 1, 1914.

National fraternity

On February 7, 1921, the Mekatina students renamed themselves inaugural members of the Alpha chapter of Theta Upsilon. Ida Shaw Martin, of the Sorority Service Bureau, is credited with outlining the plans for Theta Upsilon and perfecting its ritual.

Editorial analysis

Why this record matters

“Theta Upsilon” is worth following because a concise public description often conceals a longer documentary argument. Here, Theta, Upsilon and Defunct provides the most credible route into that argument.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Apr 19, 2026. The linked authority identifier is Q7783542. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1921, 1962, 1913 and 1914.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
