Actually modern English still has the remnants of declension (conjugation is to verb as declension is to noun); personal pronouns. I, me, mine; he, him, his; she, her, hers; it, it, its; we, us, ours; they, them, theirs. You could argue that the genitive case (possessive) is also declension in English; i.e. <noun>'s, <plural noun ending in s>'.
