The intervention of December 1855 was therefore not simply a rescue from an individual enslaver’s plan; it was a rescue from a legal and historical trajectory that would have been, for Biddy Mason and her family, catastrophic.
## What Freedom Required in Los Angeles
The city Biddy Mason lived in after 1856 was not a city that made freedom easy for Black women, whatever the constitution said. The legal protections were real but incomplete, the social environment was discriminatory in both formal and informal ways, and the economic opportunities were limited by the same barriers that limited them for all Black people in mid-nineteenth century America.
The formal legal disabilities included the testimony rule, which remained in effect in California until 1863, when it was repealed for Black witnesses (the repeal for Chinese witnesses came later). This meant that for the first seven years of her freedom, Biddy Mason lived in a state where she could not testify against a white person in court if she were victimized by one. The practical significance of this was not theoretical: it meant that the legal system provided less protection to her than to white residents of the same city.
Property ownership was legally protected from 1866 onward in a formal sense, but the informal barriers to Black economic participation were substantial. Access to credit was limited; Black entrepreneurs operated without the banking relationships that white businesspeople used for expansion; the social networks that facilitated business development and investment were largely segregated. Mason built her economic position through savings from her own labor rather than through the credit-based capital formation that characterized white entrepreneurship in the period.
