What is today called The Northwest District of The Lutheran Church—Missouri Synod was first organized as the California and Oregon District in 1887.

In 1899, a reorganization led to the name Oregon and Washington District, and, effective 1 January 1949, the name was changed to The Northwest District of the Lutheran Church—Missouri Synod.

Following each convention, a record of the proceedings was published, at first in a separate publication, then as an issue of an official periodical, and back to a separate publication again. From 1925 to 1978 the minutes of the conventions were prepared separately from the proceedings; they were handwritten through 1948 and typed through 1976. From 1978 on the minutes were included in the published proceedings. From 1942 onward a pre-convention publication (Workbook) was issued to report on district activities and to inform delegates of the matters to come before the assembly.
