How to rationalise the basicity order of phenyldiaminephenylenediamine?

Why is the basicity of parapara- > metameta- > Anilineaniline > orthoortho- for Phenyldiaminephenylenediamine?
($\mathrm{p}K_a$$\mathrm pK_\mathrm a$: ortho-9ortho: 9.53, meta-9meta: 9.12, para-7para: 7.96) I tried deducing it using resonance and inductive effects but got stuck.

Basicity Order Phenyldiamine How to rationalise the basicity order of phenyldiamine?

Why is the basicity of para->meta->Aniline>ortho for Phenyldiamine? Why is the basicity of para- > meta- > Aniline > ortho for Phenyldiamine?
($pK_a$$\mathrm{p}K_a$: ortho-9.53, meta-9.12, para-7.96) Ok I tried deducing it using resonance and inductive effects but got stuck.Help Please.
