文久

Orthographic borrowing from Japanese 文久 (Bunkyū).

文久

1. Bunkyū (Japanese era spanning from February 1861 through February 1864)

Chosen as the name of the 年号 (nengō, “era”) based on a quote from the 後漢書 (Gokanjo, “Book of the Later Han”), Volume 79, Part 2, Biographies of Confucian Scholars: Xie Gai (謝該／谢该)[1] (full Chinese source text here):

故能文武并用，成长久之计。

And it could be civil and military use, as a permanent solution.

The civil meaning here was likely chosen in reference to overtones of peace and culture.
