Concept

A coordinating conjunction has to match both the logical relation and the polarity of the two clauses it joins. English keeps one coordinating conjunction for adding a further negative statement to a clause that is already negative: nor. Nor also carries a structural signature that no other coordinating conjunction has — the clause it introduces is inverted, taking the order nor + auxiliary + subject, while every other coordinating conjunction is followed by ordinary subject + verb order.

Applying it to this sentence

1. The clause before the blank is negative: "The fierce struggle for press freedom did not end." The word in the blank has to extend that negative statement rather than reverse it.

2. The words after the blank are "was it any less diminished" — the auxiliary was stands in front of the subject it. That is inverted order, so the blank needs a conjunction that forces inversion.

3. Nor is the conjunction here that does both jobs at once: it carries the negative forward and it takes nor + auxiliary + subject.

4. The completed sentence reads: "The fierce struggle for press freedom did not end nor was it any less diminished."

Cross-check against the other conjunctions

• and is additive and is followed by ordinary subject + verb order, so "and was it any less diminished" would read as a question rather than as a continuation of the statement.

• but signals contrast and is followed by ordinary subject + verb order, so it would set the new clause against the preceding one instead of extending its negative sense.

• yet signals an unexpected turn and is followed by ordinary subject + verb order, so it cannot license the inverted "was it".

• for gives the reason for the clause that precedes it, close in meaning to because, and is followed by ordinary subject + verb order.

Here nor works as a coordinating conjunction that attaches a second negative clause to a clause which is already negative, and a clause opened by nor in this way is inverted. Watch the scope of the related correlative pair neither … nor: when it joins elements inside a single clause it does not itself trigger inversion, as in "she neither called nor wrote", whereas a clause-initial neither or nor does, as in "Neither did she call, nor did she write".
