The Holy Office orders Bruno’s works onto the Index as he is condemned
On 20 January 1600 the Congregation of the Holy Office, Clement VIII presiding, ordered that Bruno’s works be placed on the Index of Prohibited Books as it consigned him to the secular arm — a prohibition of a public, not only a killing of a body. In the causal graph this event weakens Democratic Resilience, a driver that strengthens Having a say in government — a worsening welfare path.
Read the full account
On 20 January 1600 the Congregation of the Holy Office, Clement VIII presiding, ordered that Bruno’s works be placed on the Index of Prohibited Books as it consigned him to the secular arm — a prohibition of a public, not only a killing of a body. It is not the fire itself, and it is not a Copernican-only astronomy ban. The congregation banned; he is the author banned. Execution remains the humanitarian neighbour.
Context
An Index is how a confessional state removes books from shops. Democratic-resilience here is that closure of argument, even in a world without modern democracy — the public of print is the good harmed. Readers in Protestant shops still found copies; that leak is a limit, not a reason to drop the dated prohibition. Bellarmine’s congregation role is related-person colour. The 17 February fire remains humanitarian harm, not this January prohibition; Galileo’s later Index stories are other files; a Copernicus-only ban is not this order.
That reading is an impact-path choice, not a property stored on the Fact itself.
Why it matters
High confidence on January 1600. Modest-to-medium weight. The fire remains humanitarian. 1584 print remains the earlier access. Heliocentrism-only is refused as the whole story.
Shared responsibility is part of The Holy Office orders Bruno’s works onto the Index as he is condemned. Naming Giordano Bruno does not delete co-authors, institutions, or later transmitters. The lag from 1600-01-20 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.

What the sources establish
The Vatican portal locates the Holy See whose Index machinery acted. The Catholic Encyclopedia independently records the condemnation and prohibition of Bruno’s writings. Official: https://www.vatican.va/content/vatican/en.html (opens in a new tab). Independent: https://www.newadvent.org/cathen/03016a.htm (opens in a new tab). SEP dates 20 January 1600 as the congregation’s dual order. The records establish the prohibition. They do not establish a unique later press-freedom series. A minute without Index would change the row; 17 February is not this ban; Copernicus-only is refused. A 1600 file without an Index order would change the row.
Established: on 20 January 1600 the Holy Office ordered Bruno’s works onto the Index as it condemned him. Not established: that the ban was Copernicus-only, or that 17 February is this Index act. A congregation minute without prohibition would change the row.
If a number is not in the two records named above, it is not supplied here.
Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.
Confidence is stated on the impact path, not hidden in adjectives. Index order is not the pyre of 17 February and not a heliocentrism-only ban. Mixed effects of The Holy Office orders Bruno’s works onto the Index as he is condemned are separate paths.
