The reforms serve

you should clarify what you mean.

There are several possibilities:

Intentionally: reformers wanted to serve

Unintentionally: they pursued other goals, but someone or something benefited.

Structurally: regardless of anyone's intentions, the reforms had effects that favored some development.

The third formulation is the strongest and easiest to defend because it focuses on observable historical consequences rather than difficult-to-prove motives.
